多线程之线程参数传递

任务

  将整数、字符串、CString作为参数传递给线程。

代码

#include "windows.h"
#include "iostream"
#include "atlstr.h"
using namespace std;
void Thread0(LPVOID lp) {
	for (int i = 1; i < 100; i++) {
		Sleep(1000);
		cout << "thread0 " << (int)lp << endl;
	}
}

void Thread1(LPVOID lp) {
	char *p = (char *)lp;
	Sleep(1000);
	cout << "thread1 " << *p<<endl;
}

void Thread2(LPVOID lp) {
	CString *p = (CString *)lp;
	Sleep(1000);
	cout << "thread2 " << *p<<endl;
}

HANDLE thrd0, thrd1, thrd2;
DWORD thid0, thid1, thid2;

int main(int argc, char **argv) {
	int a = 888;
	char s1[] = "abcdef";
	CString s2("abcdefgh");
	cout << "main thread" << endl;
	thrd0 = CreateThread(NULL, 0, (LPTHREAD_START_ROUTINE)Thread0, (void *)a, 0, &thid0);
	thrd1 = CreateThread(NULL, 0, (LPTHREAD_START_ROUTINE)Thread1, s1, 0, &thid1);
	thrd2 = CreateThread(NULL, 0, (LPTHREAD_START_ROUTINE)Thread2, (void *)&s2, 0, &thid2);
	Sleep(1000);
	return 0;
}

结果

输出是乱的因为未进行线程同步。
